Denon PMA 520 fuse blown

Amplifier has fuse blown (proberbly caused by playing music to loud at aux, from mp3-player). I see no damaged transistors or elco, but when replacing fuse, it will blow up right away.
What could be the Problem, or what components should I replace more?

Re: Denon PMA 520 fuse blown

Check that you are replacing the fuse with the correct type first. Fuses marked with a T following the rating are "slo blo" fuses and if a fast blow is used instead, it will fail again at turn on. Otherwise, the amp will have a fault occurring, probably in the output stages. You should refer this type of fault to a repair guy that knows HiFi. as this sort of repair needs an experienced touch.

AVR 2800 powers up and shuts off and lite blinks

Generally speaking this means a fault in the power output stage of the amp, which is the part in the pcb where the Output Transistors and the Aluminum Heatsink are, hope this helps.

Hi, i have a Denon PMA 735 R amplifier which shuts down when volume increases suddenly.

Sounds like you have output transistor problems. Does it have a red protection light that comes on when it shuts down? If it does it will need serviced.

Playing too loud music has blown my amp

maybe because your amp is overload, try to load 8 ohms single speaker per channel, then try to playing loud, if blown your amp again, the power transistors bias maybe excess to 0.6V ' if transistorized, if IC power amp, check cooling fan.

I have a Denon PMA 500V amplifier. all of the output fuses were blown so I replaced them but the unit still doesn't work. Any suggestions?

Did you checked balanced impedance?load speaker impedance vs PA output?or PA might over driven,causing a trouble on the pre-amp to power amp circuits and components damage,
need to recheck related components on the pre-driver up to main output section,

Note: That,blowing of fuses with the same rating is an indication of trouble/shorted in a circuits that driven on it,

Thanks and good luck

My Denon PMA-900V integrated amp has distortion in the left channel. When it is cold it is very minor, as it heats up and is played at louder volume the distortion is much worse.

The good news is that it's in one channel, which means you have the right channel parts to compare it with. Now the bad news whatever causing it and it's likely to be a semi-conductor (transistor or IC) has to be replaced. However finding it is easier than you might think. For a start it's going to be hot to touch. And you can get get it to stop being hot, while the amps on, so correcting the fault, for a while. You do this by spraying it with Servisol Super Freezer spray. You have to have the amp running for this. Find the left channel amp and wait while it goes bad. Then spray (one at a time) any part you suspect. If the sound returns to normal, you have found the faulty part! To prove it spray the same in the right channel. That shouldn't change.
You can get the freezer spray from your local electric parts shop (such as Maplin UK).

Hi , I have a denon pma-2000r amp in it stuck in stand by mode, i don't have original remote control, is it possible to turn it on without remote control or reset to factory settings? Many thanks!

That model shouldnt be stuck in stand-by
Are all the speakers connected?
If it wont properly turn on then there is a fault being detected. Could be disconnected speakers / bad speaker or a power supply issue

Problem with the Denon PMA 6.5 amplifier. The source selector keeps on switching between the CD and AUX inputs randomly on its own. Any idea what could be the problem?

bring a good contact cleaner from radio shack near you and apply spray with pipe in the selector and move it forward and backward.

Denon PMA-520 amplifier clicking noise

Sounds to me like a bad capacitor, but not sure. I would look inside for any slightly bulging capacitors or capacitors whose plastic wrappings have melted or shrunk or cracked (most caps are cylindrical). Please unplug first and be careful inside there and do not touch anything. I actually came across your post while looking for info on what I think is the same amp my brothers had but blew, and I was going to ask if they still had it so I could repair it. I've been very successful at repairing my electronic equipment such as Altec Lansing Model 95 speaker crossovers, power supply in Emu Emax II, and almost everything else in my studio.

DENON Input selector jumps randomly

I have a PMA-535R. Same problem but slightly different dialknob. I fixed it by spraying a contactspray and WD-40 into the knob itself. This does mean you have to disassemble the front of the amp and take out print of the dialknob. The knob has a plastic dustcovere that you will have to lift. Good luck
